The gear pumps are designed primarily for metering and transfer applications. Their modular design allows a wide variation of flow ranges with a standard parts set. These pumps provide a broad class of industrial pumps in flow ranges of 10 ml. per minute to 1 gal. per minute. All of the gear pumps are self-priming and are "constant flow" (read more)

Viking Pump has released the SG-10 Series External Gear Pumps, developed to meet increasing demand for higher capacity and pressure. The SG-10s add capacities in the 12 to 80 gpm flow range to Viking's existing spur gear family. The SG-10 is rated to 500 psi on typical industrial applications, but may be applied up to 2,500 psi depending on the application. (read more)

The compact design of Micropump's micro annular gear pumps offer precise flow rates to 288 ml/min and dispensing volumes as small as 0.25 µl. (read more)

In mechanical engineering there are a variety of transport applications for lubricants. The following pumps are designed for low to medium pressure use up to 30 bar, where centrifugal pumps are insufficient and high pressure hydraulic pumps are not yet required.

Viking's thin liquid internal gear pumps handle low viscosity liquids with high efficiency, offering many advantages in applications normally associated with centrifugal pumps. These pumps are ideal for even non-lubricating or corrosive liquids with low viscosities. (read more)

Prince Manufacturing Corporation manufactures standard and custom gear pumps to match your specifications. SP20P Series – SAE "A" Flange Gear Pump (11 Displacement Sizes) Single, Double or Triple Pumps. SP25P Series – SAE "B" Flange Gear Pump (8 Displacement Sizes) Single, Double or Triple Pumps (read more)

The internal gear pumping principle was invented by Jens Nielsen, one of the founders of Viking Pump. It uses two rotating gears which un-mesh at the suction side of the pump to create voids which allow atmospheric pressure to force fluid into the pump. (read more)

The new Viking Mag Drive® 855 Series internal gear pumps offer exceptional reliability through their robust, sealless design, which eliminates seal leakage. The pump's driver turns an outer magnet, whose force passes through a stationary O-ring-sealed canister to turn an inner magnet, which drives the pump shaft without the need for seals. (read more)

Chemsteel SM Series magnet drive, sealless gear pumps are designed to handle corrosive liquids that need to be pumped at pressures up to 110 psi. SM Series pumps are manufactured to extremely precise tolerances and are available in stainless or alloy C casing construction. Gears are available in 316SS, Alloy C, Teflon® or Peek®. (read more)

The Viking Mag Drive^® series of sealless internal gear pumps eliminate the possibility of shaft leakage by eliminating the seal. The driver turns an outer magnet, whose force passes through a hermetically sealed canister to inner magnets, which in turn drive the pump shaft. Mag drive pumps are used wherever leakage is a problem, such as acids, volatile organic chemicals, or toxic f... (read more)
